Hi folks, I am working on a WebDAV daemon (WebDAV server) written in Python which runs filesystem-related functions as the authenticated user than *root* or *nobody*.
The approach I tried to fulfill this attribute is implementing a so-called filesystem-helper which is a RPC server implements filesystem related functions. (e.g. *open*, *read*, *write*, *close*, *mkdir*, etc) The daemon act as a RPC client and spawn filesystem helpers on successful user authentication by invoking *subprocess.Popen(). *The helper invokes *os.setuid()* & *os.setgid()* immediately after spawn. Thus the helper is now running as the authenticated user and accepting requests from the deamon. My question is, (TCP/UDP) sockets are used by RPC implementations between their client-server communication conventionally, if gRPC is being used in this scenario, is it possible for the server (filesystem helper, child process) and client (daemon, parent process) communicate on *stdin*/*stdout* ?
